In late March, about 17,000 students were offered admission for the fall, leaving nearly 29,000 hopefuls out in the cold.

But the school's communications office said an e-mail was sent to all 46,377 students who applied for admission -- including the 29,000 rejects -- welcoming them to the campus.

A half-hour later, school officials said, they realized their mistake. Almost two hours after the first note went out, a second e-mail was sent, apologizing to 28,889 freshmen applicants for the mistake.

"No member of this department is more acutely aware of the emotional roller-coaster that this could cause for our applicants," Assistant Vice Chancellor Mae W. Brown said.
